Benchmark: Reduce vs map/join on list of objects

Script Preparation code:

var strings = [];
for (var i=0; i<1000; i++) {
  strings[i] = {
    id: i
  };
}

Tests:

for
var result = ""; for (var i=0; i<strings.length; i++) { result = result+','+strings[i].id; }
reduce
var result = strings.reduce(function(string, i) { return string+','+i; }, ""); result=result.substring(1);
map
var result = strings.map(el => el.id).join(',');
for of
var result = ""; for (var i of strings) { result += ','+i; }
